CRIPPLE CREEK — Big Jim’s Gambling Hall and Saloon, in operation for just three years, will close Monday night after months of financial troubles. Thirty-seven employees will lose their jobs.

Jim Druck, owner of the slots-only casino, said his business has been losing money for about a year because of the sluggish economy, a decline in Cripple Creek tourism and the emergence of Internet sweepstakes cafes.

Before it shuts its doors, it will give away about $37,000. Because the 200 slot machines at Big Jim’s have accumulated thousands of dollars in players’ bets, the casino is compelled to return the money to its customers by allowing them to play for the jackpots and allocating portions of the pool to a few lucky bettors.

Florida’s state social services agency investigated Nikolas Cruz’s home life more than a year before police say he killed 17 people at his former high school, closing the inquiry after determining that his “final level of risk is low,” despite learning that the teenager had behavioral struggles and was planning to buy a gun, according to an investigative report.
